TRANSFORM RATIO UoM Default Range
1 CT primary A 1 1-400000
2 CT secondary A 1 1-400000
3 CT N primary A 1 1-400000
4 CT N secondary A 1 1-400000
5 VT primary V 1 1-400000
6 VT secondary V 1 1-400000
Note: If Rogowski coils are used, it is not needed to set any transformation ratio.
1
- CT primary winding rated current.
2 - CT secondary winding rated current.
3 - CT Neutral primary winding rated current.
4 - CT Neutral secondary winding rated current.
5 - VT primary winding rated current.
6 - VT secondary winding rated current.
INTEGRATION UoM Default Range
1 Time interval min 15 1-2-3-5-6-10-12-15-20-30-60
2 Type - Shifting Shifting-Fixed
1 - Selection the integration time interval.
2 - Selection of average reading calculation mode:
Shifting = The instantaneous values are integrated for a period.
Fixed = Readings are integrated for a fixed rated. Every time the integration time elapses, the average value is updated with the result of the last integration.
FREQUENCY UoM Default Range
1 Fundamental Hz 50 50-60
1 - Rated frequency of the line. Possible nominal frequency values: 50 Hz or 60 Hz.
DIP / SWELL UoM Default Range
1 DIP threshold mV 190000 10-10000000
2 DIP cycles cycles 250 1-10000
3 SWELL threshold mV 270000 10-10000000
4 SWELL cycles cycles 250 1-10000
5 Interruption threshold mV 205000 10000-2000000000
6 Interruption hysteresis mV 275000 10000-2000000000
7 Storage - End memory FIFO
End memory
1 - Threshold active when the voltage is lower than value set.
2 - The duration of voltage dip. Note: 1 = 20 ms
3 - Threshold active when the voltage is higher than value set.
4 - The duration of swell over-voltages. Note: 1 = 20 ms
5 - Voltage interruption begins when the RMS value falls below this threshold. A voltage interruption ends when the voltage is equal to, or greater than, interruption
threshold plus the hysteresis.
6 - Hysteresis delay on voltage interruption.
7 - When the memory is full, the user can choose to stop the recording (end memory) or to continue overwriting the oldest records (FIFO).
WIRING / CONVENTION UoM Default Range
1 Wiring - 3 phase (4 or 3 wires) 3 phase (4 or 3 wires)
ARON
3 phase balanced
3 phase multiload balanced
Single phase
Single phase multiload
Triple single phase
Two-phase (3 wires)
2 4th input current - Measured Computed-Measured
Differential-Differential filter
3 PF convention - SIGN SIGN-IEC-IEEE
4 Setpoint timing s 1 0.1 or 1
1 - Set this parameter according to the used wiring diagram. See wiring diagrams section on the manual.
2 - The fourth current input channel (I4) is used to measure the current on the neutral line or differential current. If the CT for the neutral wire is not available, the I4
input can be calculated from the phase currents.
3 - The meter shows positive or negative power factor according to selected standard.
4 - Set the setpoint intervention time.
